1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundAngiotensin-converting enzyme inhibitors (ACEIs) are a common cause of drug-induced angioedema in the United States. Most epidemiologic ACEI angioedema data are from large multicenter clinical trials.

objectiveThe objective of this study was to identify the incidence of and risk factors for ACEI angioedema using a large integrated electronic health record (EHR).

methodsWe conducted a retrospective cohort study of all ACEI prescriptions in the outpatient setting of a large academic center between January 1, 2000, and September 30, 2008. We determined frequency, timing, and risk factors for ACEI angioedema within 5 years of prescription. All data were derived from EHR sources, with angioedema defined by EHR reactions of angioedema, swelling, edema, or lip, eye, face, tongue, throat or mouth swelling.

resultsAmong 134,945 patients prescribed an ACEI, 0.7% (n = 888) developed angioedema during the subsequent 5 years. Sex was similar but patients who developed ACEI angioedema were younger (61.5 vs 62.7 years, P = .007). Patients with ACEI angioedema were more likely to have a history of nonsteroidal anti-inflammatory drug allergy compared with patients who did not develop angioedema (7.1% vs 4.2%, P < .001). We identified a 0.07% incidence of ACEI angioedema within 1 month of prescription and a 0.23% incidence during the first year. Incidence of angioedema was relatively constant annually over the subsequent 4 years (0.10% to 0.12%).

conclusionsThe incidence of ACEI angioedema within a large EHR is consistent with large clinical trial data. We observed a persistent and relatively constant annual risk; however, angioedema risk factors and underlying genetic and pathophysiological mechanisms require further study.
